As my major is electrochemistry, and my direction is layered oxide materials, I'd like to draw some attention here. After all, these technologies still have some limitations in other fields, but they will definitely break through in the near future.
1. In-situ XRD technology In-situ X-ray powder diffraction technology has a certain history, and it can be written into a book if it is radical. Here is a brief introduction:
A. In-situ high-temperature test-put the powder sample into the XRD diffractometer, then fix the heating table and set the heating program, and the receiver will collect signals regularly, so that you can obtain the XRD spectrum of the material at different temperatures and carry out the analysis you want.
B. In-situ constant current test-friends who study batteries know this, simulating the constant current charging and discharging of batteries, and tracking and collecting structural information in real time.
2. in-situ TEM test.
In-situ transmission electron microscope observation technology, which is becoming more and more popular in recent years, is being used by more and more people. It mainly uses a high-resolution camera to quickly collect photos of samples in a short time, but the speed of machine collection is much faster than that of people. Now it is mostly used in single crystal growth and phase transition of composite materials. As for microscopic technology, in fact, in addition to in-situ tem and spherical aberration correction, ultra-high resolution transmission microscope is also very powerful, and almost atomic images can be seen. There are also atomic force microscopes that can see the molecular structure before, and China and professors used related technologies to see the existence of hydrogen bonds. Finally, nuclear magnetic resonance and Raman technology both occupy a certain position in the research of materialization, and now new applications related to them are constantly being developed. The answers on the mobile phone are relatively simple, and many of them are actually not well understood by themselves. It's just bragging. If you are free later, you must sort out the answers well, and then deepen your understanding and fill in the hole later.
